Table 5.
Results of LRP on the ERP autoencoder when keeping the distance layer input constant as in Kauffmann et al. (2020b) and when allowing a gradient flow.
| XAI | Variant | ROC | Cos |
|---|---|---|---|
| LRP | Constant | 65.3 (20.5) | –22.0 (13.9) |
| LRP | Gradient | 88.0 (12.8) | 62.2 (19.2) |
Performance improves significantly when breaking the conservation property and allowing gradient flow.
